Total Extraterrestrial Solar Irradiance (TSI) is the amount of energy from the sun, per unit area, received by every point above the Earth's atmosphere, at each instant of time; therefore, it is a quantity that varies both spatially and temporally, according to the position of a particular point on Earth and its position with respect to the Sun. A series of methodological proposals are currently available to estimate TSI on a daily basis, however, there are places such as Antarctica, where the synoptic variability is very high, therefore, it is necessary to adapt or develop a methodology that allows an energy balance to be carried out on a shorter time scale. Henceforth, the adaptability at the hourly level of the most important models proposed at the daily level will be analyzed and, finally, a methodology will be proposed to be used in studies of high spatial and temporal resolution, such as Antarctic studies at the hourly level.
